Does more volume mean deeper claims for Epoch?

Each dot is one of Epoch’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Epoch’s own 2.0 claims/patent is at or below the 8.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
